Bandgap voltage input for the ACs can not be changed when used for both ACs simultaneously
VCC voltage scaler for AC is non-linear
The ADC has up to ±2 LSB inaccuracy
ADC gain stage output range is limited to 2.4 V
Sampling speed limited to 500 ksps for supply voltage below 2.0V
ADC Event on compare match non-functional
Bandgap measurement with the ADC is non-functional when VCC is below 2.7V
Accuracy lost on first three samples after switching input to ADC gain stage
The input difference between two succeeding ADC samples is limited by VREF
Increased noise when using internal 1.0V reference at low temperature
Configuration of PGM and CWCM not as described in XMEGA A Manual
PWM is not restarted properly after a fault in cycle-by-cycle mode
BOD will be enabled at any reset
BODACT fuse location is not correct
Sampled BOD in Active mode will cause noise when bandgap is used as reference
DAC has up to ±10 LSB noise in Sampled Mode
DAC is nonlinear and inaccurate when reference is above 2.4V or VCC - 0.6V
DAC refresh may be blocked in S/H mode
Conversion lost on DAC channel B in event triggered mode
Both DFLLs and both oscillators have to be enabled for one to work
Access error when multiple bus masters are accessing SDRAM
EEPROM page buffer always written when NVM DATA0 is written
Pending full asynchronous pin change interrupts will not wake the device
